This guitarist decided to put an iPhone inside his instrument and discovered something incredible. Watch the video and keep reading to find out what causes this crazy effect.

Technology allows us to do some pretty cool things, like manipulating time, light, and motion to create stunning images. The camera of iPhone captures video in a different way than your typical camera.

It uses a rolling shutter which means the camera scans across the space, instead of taking a bunch of pictures quickly and then putting them together to make a video. Therefore, the scene isn't completely captured in a single frame and that's the reason why we see the guitar strings vibrating!
